Afterpulsing studies of low noise InGaAs/InP single-photon negative feedback avalanche diodes
Boris Korzh, Tommaso Lunghi, Kateryna Kuzmenko +2
We characterize the temporal evolution of the afterpulse probability in a free-running negative feedback avalanche diode (NFAD) over an extended range, from 300 ns to 1…
Detector-Device-Independent Quantum Key Distribution
Charles Ci Wen Lim, Boris Korzh, Anthony Martin +3
Recently, a quantum key distribution (QKD) scheme based on entanglement swapping, called measurement-device-independent QKD (mdiQKD), was proposed to bypass all detector side-chann…
Provably Secure and Practical Quantum Key Distribution over 307 km of Optical Fibre
Boris Korzh, Charles Ci Wen Lim, Raphael Houlmann +6
Proposed in 1984, quantum key distribution (QKD) allows two users to exchange provably secure keys via a potentially insecure quantum channel. Since then, QKD has attracted much at…
High-efficiency WSi superconducting nanowire single-photon detectors operating at 2.5 K
V. B. Verma, B. Korzh, F. Bussières +7
We investigate the operation of WSi superconducting nanowire single-photon detectors (SNSPDs) at 2.5 K, a temperature which is ~ 70 % of the superconducting transition temperature…
Absolute calibration of fiber-coupled single-photon detector
Tommaso Lunghi, Boris Korzh, Bruno Sanguinetti +1
We show a setup for characterising the efficiency of a single-photon-detector absolutely and with a precision better of 1%. Since the setup does not rely on calibrated devices and…
Quantum teleportation from a telecom-wavelength photon to a solid-state quantum memory
Felix Bussieres, Christoph Clausen, Alexey Tiranov +11
In quantum teleportation, the state of a single quantum system is disembodied into classical information and purely quantum correlations, to be later reconstructed onto a second sy…
